Tips for success
To achieve a more intense flavor, you can sear the chicken thighs in a pan for two minutes per side before placing them into the slow cooker. While not strictly necessary, this extra step helps to render some of the fat from the skin and adds a depth of flavor that complements the tangy mustard sauce beautifully.
If you find the sauce is too thin after the chicken is fully cooked, you can carefully remove the chicken and set the slow cooker to high with the lid off for 15 minutes.
This will allow some of the moisture to evaporate, concentrating the mustard flavors and thickening the sauce into a more luxurious consistency before serving.
Variations
- Creamy Mustard Thighs: Stir in half a cup of heavy cream or sour cream into the sauce during the final thirty minutes of cooking for a richer, velvet-like consistency that pairs wonderfully with the tangy mustard notes.
- Herbed Mustard Chicken: Add a tablespoon of fresh thyme or rosemary leaves when scattering the onions. The woody, earthy notes of these herbs provide a sophisticated contrast to the sharp flavor of the mustard.
Storage and make-ahead
- Fridge
- Store in an airtight container for up to 3 days.
- Freezer
- Freeze in a freezer-safe container for up to 2 months. Thaw in the refrigerator overnight before reheating.
- Reheat
- Reheat in a microwave-safe dish on medium power until the chicken reaches 165°F (74°C), or gently warm in a saucepan over low heat.
Store any leftovers in an airtight container in the refrigerator for up to three days. Ensure the chicken has cooled to room temperature, but do not leave it out for more than two hours after cooking.
When placing in the fridge, keep the chicken submerged in the remaining sauce to prevent the meat from drying out while stored.
You can prepare the chicken and spice mix in the slow cooker insert the night before and store it in the refrigerator. In the morning, simply pour the broth over the top, place the insert into the slow cooker base, and start the cooking process. This is an excellent way to save time during busy work days.
Serving ideas
Serve these deviled chicken thighs over a bed of fluffy mashed potatoes, steamed rice, or with a side of crusty bread to soak up the tangy mustard sauce.
A crisp green salad with a light vinaigrette provides a refreshing contrast to the richness of the braised chicken, balancing the meal perfectly for a satisfying dinner.
For a more complete presentation, garnish the dish with a sprinkle of fresh parsley or finely chopped chives just before serving.
The brightness of the fresh herbs cuts through the depth of the mustard sauce, adding a vibrant visual appeal and a subtle layer of freshness that complements the savory, tender chicken thighs.

Easy Slow Cooker Deviled Chicken Thighs with Tangy Mustard Sauce

Ingredients
- 6 bone-in skin-on chicken thighs
- 1 yellow onion, sliced
- 2 tbsp mustard spice mix
- 1 cup mustard-yellow broth
Instructions
- Place the bone-in skin-on chicken thighs into the slow cooker insert, skin side facing upward to ensure even cooking. Arrange them in a single layer if possible, tucking them snugly against one another to maintain consistent heat distribution throughout the cooking process.
- Scatter the sliced yellow onion evenly over the chicken thighs. Sprinkle the mustard spice mix generously over the top of the onions and chicken, ensuring all pieces are well-coated. Finally, pour the mustard-yellow broth over the ingredients, allowing it to settle at the base of the insert to create a flavorful braising liquid.
- Cover the slow cooker and cook on low for 4 to 6 hours or on high for 3 hours. Once the chicken reaches an internal temperature of 165°F (74°C), remove the thighs carefully. Let the chicken rest for at least 5 minutes before serving to allow the juices to redistribute properly throughout the meat, ensuring maximum tenderness.
